All Event sites require an organiser to specify a location for the software to be able to find events in specific locations. The same also applies to Virtual events.
Zzjimi is no different, we do require a location to be specified for Podcasts or Virtual events, for our site software to be able to match your event/activtiy to our User's Wishlists.
However, you do not have to enter your specific address, you could just input a Town, City or place name and our software should work for you. Remember to choose the nearest option to your location as it appears on the dropdown selection.
As a tip - if you want your Podcast or Virtual event to be found across a greater distance why don't you create duplicate posts, but use a different location for each, spreading these out nationally (or even globally), could really draw a bigger audience!
